You can use Kobo Store Credit to buy eGifts (if available in your area), eBooks, and audiobooks from the Kobo Store. Store Credit can not be used to purchase eReaders, accessories, subscription services, or pre-order books.
When available, Store Credit is applied to your purchase automatically. If you don’t have enough Store Credit to cover the purchase, it can be combined with your usual payment method, such as a credit card, to complete the purchase.
You’ll receive Kobo Store Credit when you return an eBook or redeem a Kobo Gift Card.
Store credit never expires, as long as you have a Kobo account.
